Abstract

A helmet includes a helmet body having a front opening, a closing member attached to the outer side of the helmet body so as to close the opening, and an exterior member attached. The helmet body includes a first outer surface, a first attachment surface to which the closing member is attached, and a second attachment surface which is located between the first outer surface and the first attachment surface and to which the exterior member is attached. The exterior member includes a second outer surface continued to the curved surface shape of the first outer surface, and a side surface. The second outer surface and the side surface form a first angle toward inside of the helmet body. The first outer surface and the second attachment surface form a second angle toward inside of the helmet body. The second angle is larger than the first angle.

First claim

The invention claimed is:

1 . A helmet, comprising:
a helmet body including a front opening; a closing member attached to an outer side of the helmet body to close the front opening; and an exterior member attached to the outer side of the helmet body adjacent to the closing member, wherein the helmet body includes a first outer surface having a curved shape, a first attachment surface to which the closing member is attached, and a second attachment surface, located between the first outer surface and the first attachment surface, to which the exterior member is attached, the exterior member includes a second outer surface having a curved shape continuous with the first outer surface having the curved shape, and a side surface extending from one end of the second outer surface toward the helmet body, the second outer surface and the side surface are formed at a first angle at a side located toward an inner side of the helmet body, the first outer surface and the second attachment surface are formed at a second angle where a boundary of the first outer surface and the second attachment surface extends at a side located toward the inner side of the helmet body, and the second angle is greater than the first angle.

2 . The helmet according to claim 1 , wherein the second angle is greater than or equal to 90 degrees and less than 180 degrees.

3 . The helmet according to claim 1 - or 2 , wherein
the first attachment surface and the second attachment surface are formed at a third angle where a boundary of the first attachment surface and the second attachment surface extends at a side located toward the inner side of the helmet, and the third angle is greater than the first angle.

4 . The helmet according to claim 3 , wherein the third angle is in a range of 90 degrees to 270 degrees.

5 . The helmet according to claim 1 , wherein the helmet body has a thickness in a normal direction at a part defining the second attachment surface that is 0.8 times to 2 times a thickness in a normal direction at a part defining the first attachment surface.

6 . The helmet according to claim 1 , wherein
the exterior member includes an attached surface that connects the second outer surface to the side surface and faces the second attachment surface, and the attached surface includes a recess that does not contact the second attachment surface.

7 . The helmet according to claim 1 , wherein
the helmet body further includes a bottom opening, open downward, through which a head of a wearer is fitted, the front opening is connected to the bottom opening at a front lower side of the helmet body, and the closing member includes
a shield that closes an upper portion of the front opening and is light-transmissive, and
a chin guard that closes a lower portion of the front opening and is separate from the helmet body.
